Signs and Symptoms

The symptoms associated with nontuberculous mycobacteria (NTM) infections depend on which part(s) of the body are involved. Lung (pulmonary) infections may cause tuberculosis-like symptoms, including:

  • Chronic cough, sometimes with bloody sputum
  • Fever
  • Chills
  • Weight loss
  • Weakness, fatigue

Skin-related NTM infections may cause persistent sores, boils, ulcers, and granulomas. Infections affecting lymph nodes may cause inflammation in the node(s).

All of these symptoms may also be seen in a variety of other conditions. The diagnosis of most NTM infections depends on the positive identification of mycobacteria in body fluids or tissues.
